"The'jcasing 39 my be mounted in any convenient manner but is shown h'erereceiyed'in sleeyes olf tilh's tl fix ed to the bottom of 'th'tanksl'O and 11. The'c'rosspi'pe 39 is provided with a narrow elongetedsiot 42"inits lower side, thijongh" which e broad fiector.

The approximate amount of water W Y fiat stream of water may be discharged over the deflector 36 and into one of the tanks 10 or 11.

Having described the construction of my improved measuring machine the method of operation is as follows Assuming the parts to be in the posi' tion shown in Figs. 1 and 6, the water will continue to flow into the tank 11 until the water level reaches the top of the overflow pipe 13. Water will then flow down through the pipe 13 to the discharge trough 23 and will collect in the lower end of the trough above the gate valve 28. The trough 23 and 24 and all connected parts are carefully balanced so that only a small amount of water is necessary in the end of one. of the troughs to reverse the position thereof, swinging the deflector 86 from the position shown in full lines in Fig. 6 to the dotted lines shown in said figure. The parts. at the moment of reversal are all shown in Fig. 7.

Rocking movement of the troughs is limited by stops 43 (Fig. 5) at both ends of the machine and the permitted movement is not sufficient to overcome the incline of the bottom of the troughs, so that the ports 27 and valves 28 are always at thelower ends of the troughs, whether in filling .or discharge position.

As the right hand or deeper end of the trough 23 is depressed the valve 28 is relatively raised to open the port 27 and at the same time the associated valve 16 is raised to open the port 15 in the bottom of the tank 11. Water will then flow through the discharge port 15 to the trough 23 and will escape therefrom through the open port 27.

In this way the trough 23 and tank 11 Will both be entirely freed of water while the measuring tank 10 is being filled to the level of its discharge pipe. The parts will then be a second time reversed and this action will continue indefinitely, discharging a measured quantity of water at each reversal of the machine.

A numbering device 45 (Fig. 5) may be connected by a link 46 to the rocking trough structure, thus recording the number of reversals of the machine. By calibrating the machine to determine the exact amount of water or other liquid discharged by the machine at each reversal, the total quantity of water passing through the machine may be easily determined after inspection of the numbering device 45.

The deflector 36 is made of suflicient weight so that it will slightly retard the reversal of the discharge troughs and will hold them in one position until a sufficient amount 'ofwater collects in one of the troughs to overcome the unbalanced weight of the de shown inthe trough 23 in Fig. 7 represents the weight necessary to overcome the deflector.

Having thus described my invention and the operation and advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the cl aims but what I claim is:

l. A water measuring machine having a pair of measuring tanks, a pair of discharge troughs, said troughs being pivotally mounted beneath said tanks and having their bottoms always inclined downward in opposite directions but at different angles in different operative positions of said troughs, means to deliver a relatively small quantity of water to its associated trough when one of said measuring tanks is filled to a predetermined point, and connections actuated by the weight of said overflow water efieotive to open discharge valves in said tank and trough and to deflect the flow of water to the second tank.

2. A water measuring machine comprising a pair of measuring tanks, each having an overflow pipe and a discharge valve, a discharge trough pivotally mounted beneath each tank and having an inclined bottom with a discharge valve at its lower end, a water supply, means to direct said water supply to either tank, and connections from said troughs to said valves and to said directing means, reversal of said troughs being occasioned by the accumulation of water from the overflow pipe of one of said tanks at the lower end of its associated trough and such reversal being efiective to deflect the water supply to the second tank to open the discharge valves in the filled tank and its associated trough, and to close the discharge valves in the second tank and trough.

3. A water measuring machine comprising a pair of measuring tanks arranged side by side and each having an overflow pipe and a discharge valve at the opposite ends thereof, the overflow pipe in each tank being at the end of the tank adjacent the discharge valve in the other tank, a discharge trough pivotally mounted beneath each tank and having an inclined bottom with a discharge valve at its lower end, said bottoms being always inclined downwardly in a fixed direction but at diiierent'angles in difi'erent positions of said troughs, a water supply, a deflector to direct said water supply to either tank, and connections from said troughs to said valves and to said deflector, whereby reversal of said troughs by the accumulation of overflow water in one of said troughs is effective to open the discharge valves in the filled tank and its associated trough, to close the valves in the other tank and trough, and to deflect the water supply to the emptied tank.

a. A water measuring machine comprising a pair of measuring tanks, each having ill) an overflow pipe and a discharge valve, a discharge trough pivotally mounted beneath each tank and having an inclined bottom with a discharge valve at its lower end, a stop to limit rocking movement of said troughs to prevent reversal of the inclination of the bottoms thereof, means to direct a supply of Water to either tank, valves controlling the accumulation of Water in said tanks and troughs alternately in pairs, and means regulated by the rocking movement of said troughs and effective to reverse the Water delivery to an empty tank and to open the valves in a filled tank and its associated trough, to discharge the Water therein.

In testimony whereof I have hereunto affixed my signature,

JOHN E. RUNNELLS.
